Santo António de Cascais Tower, Fortified tower in Cascais, Portugal.
The Santo António de Cascais Tower stands with thick stone walls, limited window openings, and four watchtowers at each corner of its square structure.
King John II ordered the construction of this tower in 1488 as part of a defense network protecting Lisbon's port alongside the towers of São Sebastião and Belém.
The tower represents Portuguese maritime defense architecture and forms part of the Citadel of Cascais, which later became a royal summer residence.
While the interior remains closed to visitors, the exterior structure can be viewed from multiple points along the Cascais-Estoril coastal path.
The tower contains an underground cistern shaped like the letter L, discovered during archaeological excavations in 1986 by Margarida Ramalho.
